Happened the same to me, after checking my connections I found that it was a loose wire between the USB-serial converter TX pin and the ESP32 RX pin.

I recommend trying a different USB cable. I was getting the same error that you listed, but tried other cables until I found one that worked.

It seems as though some USB cables are good for charging/powering devices but don't have all the other pins (correctly?) wired. Hopefully this is all your problem too.

Good luck and please update this to either say it worked for you or provide other details on the problem if not.

check if the TX or RX traces/pins are connected up properly, maybe you accidentally scratched a trace on your board or something like that which causes the TX pin to be unavailable to the programming chip
